However, your favorite celebs didn't always look like you'd assume in the days before they were famous, whether it was Amy Poehler's wild 1980s hairdo or Hillary Clinton's hippy appearance. You never would have thought they could put on such costumes.
Some actors were once young, awkward, and astoundingly normal — or at least beholden to questionable fashion trends in the 80s and 90s. On the other hand, some were so majestically good-looking that you will be hypnotized. And you can’t believe they were this hot in the past.
Read on to see these incredible photos of famous actors when they were young. I guarantee you will not believe in your eyes that they used to be this hot, and I mean smoking hot.
